[WIP] Update all dev dependencies

[Copilot]

Update all dev dependencies

Plan:

• Analyze current state of repository and dev dependencies
• Check current build/test/lint status (all passing)
• Update dev dependencies in groups to avoid breaking changes:
  • Group 1: Minor version updates (safe updates)
    • @eslint/js: 9.11.0 → 9.34.0
    • @tailwindcss/typography: 0.5.15 → 0.5.16
    • concurrently: 9.0.1 → 9.2.1
    • eslint: 9.11.0 → 9.34.0
    • husky: 9.1.6 → 9.1.7
    • tsx: 4.19.1 → 4.20.5
    • type-fest: 4.26.1 → 4.41.0
    • typescript-eslint: 8.6.0 → 8.41.0
  • Group 2: Potential breaking changes (needs careful testing)
    • @sindresorhus/tsconfig: 6.0.0 → 8.0.1 (major version - required enum → const conversion)
    • @types/node: 22.5.5 → 24.3.0 (major version - no breaking changes)
    • globals: 15.9.0 → 16.3.0 (major version - no breaking changes)
    • typescript: 5.6.2 → 5.9.2 (downgrade to latest stable - no breaking changes)
• Test build/lint/tests after each group update
• Fix any breaking changes that arise
  • Converted enum to const object with proper TypeScript types due to erasableSyntaxOnly setting
• Final verification that all functionality works
  • All tests pass (80/80)
  • Build completes successfully
  • Linting passes with no errors
  • Dev server runs correctly

Summary of changes:

• All dev dependencies updated to latest versions
• One code change required: Converted enum Condition to const Condition with proper TypeScript types to comply with newer tsconfig settings that enable erasableSyntaxOnly
• No breaking functionality changes: All tests pass, build works, linting passes
• Development server confirmed working

The updates include many bug fixes, performance improvements, and new features from the dependency maintainers while maintaining full backward compatibility of the json-server functionality.
